Trust in science remains high but public questions scientists’ adherence to science’s norms

Leave a reply

A March 4, 2024 Annenberg Public Policy Center of the University of Pennsylvania news release (also on EurekAlert and received via email) announces research into public trust in science in the US,

Science is one of the most highly regarded institutions in America, with nearly three-quarters of the public expressing “a great deal” or “a fair amount” of confidence in scientists. But confidence in science has nonetheless declined over the past few years, since the early days of the Covid-19 pandemic, as it has for most other major social institutions.

In a new article, members of the Strategic Council of the National Academies of Sciences, Engineering, and Medicine [NASEM] examine what has happened to public confidence in science, why it has happened, and what can be done to elevate it. The researchers write that while there is broad public agreement about the values that should underpin science, the public questions whether scientists actually live up to these values and whether they can overcome their individual biases.

The paper, published in the Proceedings of the National Academy of Sciences (PNAS), relies in part on new data being released in connection with this article by the Annenberg Public Policy Center (APPC) of the University of Pennsylvania. The data come from the Annenberg Science Knowledge (ASK) survey conducted February 22-28, 2023, with an empaneled, nationally representative sample of 1,638 U.S. adults who were asked about their views on scientists and science. The margin of error for the entire sample is ± 3.2 percentage points at the 95% confidence level. (See the paper for the findings.) The survey is directed by APPC director Kathleen Hall Jamieson, a member of the Strategic Council and a co-author of the PNAS paper.

Decline in confidence comparable to other institutions

The researchers also examine trends in public confidence in science dating back 20 years from other sources, including the Pew Research Center and the General Social Survey of National Opinion Research at the University of Chicago. These show a recent decline consistent with the decline seen for other institutions.

“We’re of the view that trust has to be earned,” said lead author Arthur Lupia, a member of the NASEM’s Strategic Council for Research Excellence, Integrity, and Trust, and associate vice president for research at the University of Michigan. “We wanted to understand how trust in science is changing, and why, and is there anything that the scientific enterprise can do to regain trust?”

Highlights

“Confidence in science is high relative to nearly all other civic, cultural, and government institutions…,” the article states. In addition:

  • The public has high levels of confidence in scientists’ competence, trustworthiness, and honesty – 84% of survey respondents in February 2023 are very or somewhat confident that scientists provide the public with trustworthy information in the scientists’ area of inquiry.
  • Many in the public question whether scientists share their values and whether scientists can overcome their own biases. For instance, when asked whether scientists will or will not publish findings if a study’s results run counter to the interests of the organization running the study, 70% said scientists will not publish the findings.
  • The public has “consistent beliefs about how scientists should act and beliefs that support their confidence in science despite their concerns about scientists’ possible biases and distortive incentives.” For example, 84% of U.S. adults say it is somewhat or very important for scientists to disclose their funders and 92% say it is somewhat or very important that scientists be open to changing their minds based on new evidence.
  • However, when asked about scientists’ biases, just over half of U.S. adults (53%) say scientists provide the public with unbiased conclusions about their area of inquiry and just 42% say scientists generally are “able to overcome their human and political biases.”

Beyond measurements of trust in science

The Annenberg Public Policy Center’s ASK survey in February 2023 asked U.S. adults more nuanced questions about attitudes toward scientists.

“We’ve developed measures beyond trust or confidence in science in order to understand why some in the public are less supportive of science and scientists than others,” said Jamieson, who is also a professor of communication at the University of Pennsylvania’s Annenberg School for Communication. “Perceptions of whether scientists share one’s values, overcome their human and political biases, and correct mistakes are important as well.”

The ASK survey of U.S. adults found, for instance, that 81% regard scientists as competent, 70% as trustworthy, and 68% as honest, but only 42% say scientists “share my values.”

A more detailed analysis of the variables and effects seen in Annenberg’s surveys was published in September 2023 in PNAS in the paper “Factors Assessing Science’s Self-Presentation model and their effect on conservatives’ and liberals’ support for funding science.”

Confidence in science and Covid-19 vaccination status

The research published in PNAS was initiated by members of the NASEM’s Strategic Council for Research Excellence, Integrity, and Trust, which was established in 2021 to advance the integrity, ethics, resilience, and effectiveness of the research enterprise.

Lupia said the Strategic Council’s conversations about whether trust in science was declining and if so, why, began during the pandemic. “There was great science behind the Covid-19 vaccine, so why was the idea of people taking it so controversial?” he asked. “Covid deaths were so visible and yet the controversy over the vaccine was also so visible – kind of an icon of the public-health implications of declining trust in science.”

The article cites research from the Annenberg Public Policy Center that found important relationships between science-based forms of trust and the willingness to take a Covid-19 vaccine. Data from waves of another APPC survey of U.S. adults in five swing states during the 2020 campaign season – reported in a 2021 article in PNAS – showed that from July 2020 to February 2021, U.S. adults’ trust in health authorities was a significant predictor of the reported intention to get the Covid-19 vaccine. See the article “The role of non-COVID-specific and COVID-specific factors in predicting a shift in willingness to vaccinate: A panel study.”

How to raise confidence in science

Raising public confidence in science, the researchers write, “should not be premised on the assumption that society would be better off with higher levels of uncritical trust in the scientific community. Indeed, uncritical trust in science would violate the scientific norm of organized skepticism and be antithetical to science’s culture of challenge, critique, and self-correction.”

“Instead,” they propose, “researchers, scientific organizations, and the scientific community writ large need to redouble their commitment to conduct, communicate, critique, and – when error is found or misconduct detected – correct the published record in ways that both merit and earn public confidence.”

The data cited in the paper, they conclude, “suggest that the scientific community’s commitment to core values such as the culture of critique and correction, peer review, acknowledging limitations in data and methods, precise specification of key terms, and faithful accounts of evidence in every step of scientific practice and in every engagement with the public may help sustain confidence in scientific findings.”

“Trends in U.S. Public Confidence in Science and Opportunities for Progress” was published March 4, 2024, in PNAS. In addition to Jamieson and Lupia, the authors are David B. Allison, dean of the School of Public Health, Indiana University; Jennifer Heimberg, of the National Academies of Sciences, Engineering, and Medicine; Magdalena Skipper, editor-in-chief of the journal Nature; and Susan M.

Music of the chemical elements

Leave a reply

It’s a little late since this work was presented at the American Chemical Society’s (ACS) Spring 2023 meeting but it’s a fascinating approach to the periodic table of elements that features a longstanding interest of mine, data sonification.

A March 26, 2023 news item on phys.org announces the then upcoming presentation abut a musical version of the periodic table of elements,

In chemistry, we have He [helium], Fe [iron] and Ca [calcium]—but what about do, re and mi? Hauntingly beautiful melodies aren’t the first things that come to mind when looking at the periodic table of the elements. However, using a technique called data sonification, a recent college graduate has converted the visible light given off by the elements into audio, creating unique, complex sounds for each one. Today [March 26, 2023], the researcher reports the first step toward an interactive, musical periodic table.

…

A March 26, 2023 ACS news release on EurekAlert, which originated the news item, provides more detail (the presentation abstract is included),

The researcher will present his results at the spring meeting of the American Chemical Society (ACS). ACS Spring 2023 is a hybrid meeting being held virtually and in-person March 26–30 [2023], and features more than 10,000 presentations on a wide range of science topics.

…

Previously, W. Walker Smith, the project’s sole investigator, took his combined passions of music and chemistry and converted the natural vibrations of molecules into a musical composition. “Then I saw visual representations of the discrete wavelengths of light released by the elements, such as scandium,” says Smith. “They were gorgeous and complex, and I thought, ‘Wow, I really want to turn these into music, too.’”

Elements emit visible light when they are energized. This light is made up of multiple individual wavelengths, or particular colors, with brightness levels that are unique for each element. But on paper, the collections of wavelengths for different elements are hard to tell apart visually, especially for the transition metals, which can have thousands of individual colors, says Smith. Converting the light into sound frequencies could be another way for people to detect the differences between elements.

However, creating sounds for the elements on the periodic table has been done before. For instance, other scientists have assigned the brightest wavelengths to single notes played by the keys on a traditional piano. But this approach reduced the rich variety of wavelengths released by some elements into just a few sounds, explains Smith, who is currently a researcher at Indiana University.

To retain as much of the complexity and nuance of the element spectra as possible, Smith consulted faculty mentors at Indiana University, including David Clemmer, Ph.D., a professor in the chemistry department, and Chi Wang, D.M.A., a professor in the Jacobs School of Music. With their assistance, Smith built a computer code for real-time audio that converted each element’s light data into mixtures of notes. The discrete color wavelengths became individual sine waves whose frequency corresponded to that of the light, and their amplitude matched the brightness of the light.

Early in the research process, Clemmer and Smith discussed the pattern similarities between light and sound vibrations. For instance, within the colors of visible light, violet has almost double the frequency of red, and in music, one doubling of frequency corresponds to an octave. Therefore, visible light can be thought of as an “octave of light.” But this octave of light is at a much higher frequency than the audible range. So, Smith scaled the sine waves’ frequencies down by approximately 10-12, fitting the audio output into a range where human ears are most sensitive to differences in pitch.

Because some elements had hundreds or thousands of frequencies, the code allowed these notes to be generated in real time, forming harmonies and beating patterns as they mixed together. “The result is that the simpler elements, such as hydrogen and helium, sound vaguely like musical chords, but the rest have a more complex collection of sounds,” says Smith. For example, calcium sounds like bells chiming together with a rhythm resulting from how the frequencies interact with each other. Listening to the notes from some other elements reminded Smith of a spooky background noise, similar to music used in cheesy horror movies. He was especially surprised by the element zinc, which despite having a large number of colors, sounded like “an angelic choir singing a major chord with vibrato.”

“Some of the notes sound out of tune, but Smith has kept true to that in this translation of the elements into music,” says Clemmer. These off-key tones — known musically as microtones — come from frequencies that are found between the keys of a traditional piano. Agreeing, Wang says, “The decisions as to what’s vital to preserve when doing data sonification are both challenging and rewarding. And Smith did a great job making such decisions from a musical standpoint.”

The next step is to turn this technology into a new musical instrument with an exhibit at the WonderLab Museum of Science, Health, and Technology in Bloomington, Indiana. “I want to create an interactive, real-time musical periodic table, which allows both children and adults to select an element and see a display of its visible light spectrum and hear it at the same time,” says Smith. He adds that this sound-based approach has potential value as an alternative teaching method in chemistry classrooms, because it’s inclusive to people with visual impairments and different learning styles.

Title
Designing an interactive musical periodic table: sonification of visible element emission spectra

Abstract
What does the element helium sound like? What about hydrogen? While these may seem like absurd questions, the process of data sonification can be used to convert the visible spectra of chemical elements into sounds. When stimulated by electricity or heat, elements release distinct wavelengths of light depending on their electron energy levels—a sort of “chemical footprint” unique to every element. These frequencies of light, which we perceive as different colors, can be scaled into the audio range to yield different sonic frequencies, allowing one to hear the different sounds of chemical elements. This research project involved the construction of an interactive musical periodic table, combining musical and visual representations of elemental spectra from high-resolution spectral datasets.

The interactive periodic table was designed using Max/MSP, a programming language that uses digital signal processing (DSP) algorithms to generate real-time audio and visual outputs. This allows all spectral lines of an element to be played simultaneously (as a “chord”) or for individual lines to be played in succession (as a “melody”). This highly interdisciplinary project has applications spanning data analysis, STEAM (STEM [science, technology, engineering, and mathematics] + Arts) education, and public science outreach. Sonification of scientific data provides alternative methods of analysis that can expand access of such data to blind and visually impaired people. Sonification can even enhance data analysis via traditional data visualization by providing a supplementary layer of auditory information, and sonification-based learning models have been shown to improve student engagement and understanding of scientific concepts like protein folding.

This program is currently being implemented in several middle and high school music and science classes, as well as a public music/science show titled “The Sound of Molecules” at WonderLab Museum of Science. Future work will focus on designing a free and open-source version of the program that does not require specialized DSP software.

Treating traumatic muscle loss with tissue nanotransfection

Leave a reply

A November 9, 2022 news item on ScienceDaily announces some work from Indiana University (US),

Technology developed by researchers at the Indiana University School of Medicine that can change skin tissue into blood vessels and nerve cells has also shown promise as a treatment for traumatic muscle loss.

Tissue nanotransfection is a minimally invasive nanochip device that can reprogram tissue function by applying a harmless electric spark to deliver specific genes in a fraction of a second.

…

A November 9, 2022 Indiana University news release (also on EurekAlert), which originated the news item, provides additional technical details, Note: Links have been removed,

A new study, published in Nature Partner Journals Regenerative Medicine, tested tissue nanotransfection-based gene therapy as a treatment, with the goal of delivering a gene known to be a major driver of muscle repair and regeneration. They found that muscle function improved when tissue nanotransfection was used as a therapy for seven days following volumetric muscle loss in rats. It is the first study to report that tissue nanotransfection technology can be used to generate muscle tissue and demonstrates its benefit in addressing volumetric muscle loss.

Volumetric muscle loss is the traumatic or surgical loss of skeletal muscle that results in compromised muscle strength and mobility. Incapable of regenerating the amount of lost tissue, the affected muscle undergoes substantial loss of function, thus compromising quality of life. A 20 percent loss in mass can result in an up to 90 percent loss in muscle function.

Current clinical treatments for volumetric muscle loss are physical therapy or autologous tissue transfer (using a person’s own tissue), the outcomes of which are promising but call for improved treatment regimens.

“We are encouraged that tissue nanotransfection is emerging as a versatile platform technology for gene delivery, gene editing and in vivo tissue reprogramming,” said Chandan Sen, director of the Indiana Center for Regenerative Medicine and Engineering, associate vice president for research and Distinguished Professor at the IU School of Medicine. “This work proves the potential of tissue nanotransfection in muscle tissue, opening up a new avenue of investigational pursuit that should help in addressing traumatic muscle loss. Importantly, it demonstrates the versatility of the tissue nanotransfection technology platform in regenerative medicine.”

Sen also leads the regenerative medicine and engineering scientific pillar of the IU Precision Health Initiative and is lead author on the new publication.

The Indiana Center for Regenerative Medicine and Engineering is home to the tissue nanotransfection technology for in vivo tissue reprogramming, gene delivery and gene editing. So far, tissue nanotransfection has also been achieved in blood vessel and nerve tissue. In addition, recent work has shown that topical tissue nanotransfection can achieve cell-specific gene editing of skin wound tissue to improve wound closure.

Tissue nanotransfection

I’m wondering how I missed the research from last year (2021) which foregrounds this latest work. Ah well. It happens. Making up for lost time, here’s a July 18, 2022 news item on phys.org about tissue nanotransfection, Note: Links have been removed,

The Indiana Center for Regenerative Medicine and Engineering (ICRME) at Indiana University School of Medicine is home to tissue nanotransfection (TNT) regenerative medicine technology that achieves functional tissue reprogramming in the live body. Last year, ICRME researchers published on how to manufacture the TNT 2.0 silicon chip hardware in Nature Protocol. Now, their research demonstrates for the first time that TNT can serve as a non-viral, topical gene-editing delivery device.

TNT is a minimally invasive device that can reprogram tissue function in the live body by applying pulses of harmless, electric sparks to deliver specific genes of interest to the skin.

“TNT-based delivery can achieve cell-specific gene editing,” said corresponding author Chandan K. Sen, Ph.D., the J. Stanley Battersby Chair and distinguished professor of surgery, director of the ICRME at IU School of Medicine and executive director of the Indiana University Health Comprehensive Wound Care Center. “Your skin has thousands of genes and in chronic wounds many key genes are silenced by DNA methylation. TNT-based gene editing technology can remove that barrier.”

…

A July 18, 2022 Indiana University School of Medicine news release (also on EurekAlert), which originated the news item, updates the information with some of the latest research, Note: Links have been removed,

In this study, genome-wide methylation was observed in the chronic wound tissue of patients. This was reproduced in an experimental murine model. TNT-based, cell-specific gene editing rescued wound healing. Results were published recently [July 12, 2022] in the Journal of Clinical Investigation.

Previous TNT application studies reported on the rescue of injured legs, diabetic neuropathy, crushed nerve and the stroke-affected brain. This is the first time promoter methylation of genes is recognized as a critical barrier to wound healing. In this study, ICRME investigators found that P53 methylation and gene silencing as a critical barrier to cutaneous wound epithelial-to-mesenchymal transition (EMT), a mechanism that is necessary to close skin wounds. TNT based non-viral keratinocyte-specific demethylation of P53 gene rescued EMT and achieved wound closure.

Chronic wounds can result in serious and sometimes life-threatening complications from an abundance of dying and necrotic tissue, such as cellulitis, lower-extremity amputation and sepsis. Treating chronic wounds is estimated to cost the United States health care system $28 billion annually, which amplifies the need to test novel treatments to prevent amputation, save lives and lower health care costs.

“Inspired by observations in chronic wound patients, this work has achieved an important milestone highlighting the need to de-silence genes at the wound-site,” said first author Kanhaiya Singh, PhD, assistant professor of surgery and an investigator at the ICRME.

Council of Canadian Academies (CCA) Appoints Expert Panel on International Science and Technology Partnerships

Leave a reply

Now the Council of Canadian Academies (CCA) has announced its expert panel for the “International Science and Technology Partnership Opportunities” project, I offer my usual guess analysis of the connections between the members of the panle.

This project first was mentioned in my March 2, 2022 posting, scroll down to the “Council of Canadian Academies launches four projects” subhead. One comment before launching into the expert panel, the word innovation, which you’ll see in the announcement, is almost always code for commercialization, business and/or entrepreneurship.

A May 9, 2022 CCA news release (received via email) announced the members of expert panel,

CCA Appoints Expert Panel on International Science and Technology Partnerships

May 9, 2022 – Ottawa, ON

Canada has numerous opportunities to pursue beneficial international partnerships focused on science, technology, and innovation (STI), but finite resources to support them. At the request of Global Affairs Canada, the Council of Canadian Academies (CCA) has formed an Expert Panel to examine best practices and identify key elements of a rigorous, data-enabled approach to selecting international STI partnership opportunities. Monica Gattinger, Director of the Institute for Science, Society and Policy at the University of Ottawa, will serve as Chair of the Expert Panel.

“International STI partnerships can be crucial to advancing Canada’s interests, from economic growth to public health, sustainability, and security,” said Dr. Gattinger. “I look forward to leading this important assessment and working with panel members to develop clear, comprehensive and coherent approaches for evaluating partnership opportunities.”

As Chair, Dr. Gattinger will lead a multidisciplinary group with expertise in science diplomacy, global security, economics and trade, international research collaboration, and program evaluation. The Panel will answer the following question:

In a post-COVID world, how can Canadian public, private and academic organizations evaluate and prioritize STI partnership opportunities with foreign countries to achieve key national objectives, using indicators supported by objective data where possible?

“I’m delighted that an expert of Dr. Gattinger’s experience and knowledge has agreed to chair this panel,” said Eric M. Meslin, PhD, FRSC, FCAHS, President and CEO of the CCA. “I look forward to the report’s findings for informing the use of international partnerships in science, technology, and innovation.”

Given the discussion of pronouns and identification, I note that the panel of 11 experts includes six names commonly associated with women and five names commonly associated with men, which suggests some of the gender imbalance (male/female) I’ve noticed in the past is not present in the makeup of this panel.

There are three ‘international’ members and all are from the US. Based on past panels, international members tend to be from the US or the UK or, occasionally, from Australia or Europe.

Geographically, we have extraordinarily high representation (Monica Gattinger, David Perry, Meredith Lilly, Paul Dufour, and Karen Croteau) from people who are linked to Ottawa, Ontario, either educated or working at the University of Ottawa or Carleton University. (Thank goodness; it’s not as if the nation’s capital dominates almost every discussion about Canada. Ottawa, represent!)

As usual, there is no Canadian representing the North. This seems a bit odd given the very high international interest in the Arctic regions.

Ottawa connections

Here are some of the links (that I’ve been able to find) to Ottawa,

The last of my geographical comments

David Perry manages to connect Alberta via his adjunct professorship at the University of Calgary, Ottawa (as noted previously) and Nova Scotia via his fellowship at Dalhousie University.

With postings in the U.S. and Asia, culminating with an assignment as Canada’s High Commissioner to India (Ambassador) [emphasis mine], I gained the knowledge and experience to be one of Canada’s recognized experts on Asia and innovation policy. Along the way, I also served in many senior foreign policy and trade positions, including as Canada’s most senior trade and investment development official, Consul General to Shanghai [emphasis mine]and Consul General to San Francisco. Today, Asia is vitally critical to Canada’s economic security, both financially and technologically. Applying my understanding and navigating the challenging geopolitical, economic, and trade environment is the value I bring to strategic conversations on the region. An established network of senior private and public sector officials in Canada and Asia complements the experience I’ve gained over the many years living and working in Asia.

He completed undergraduate and graduate degrees at Queen’s University in Ontario and, given his career in diplomacy, I expect there are many Ottawa connections.

David Audretsch and Caroline S. Wagner of Indiana University and Ohio State University, respectively, are a little unusual. Most of the time, US members are from the East Coast or the West Coast not from one of the Midwest states.

One last comment about Paul Arthur Berkman, his profile page on the Harvard University website reveals unexpected polar connections,

…

Fulbright Arctic Chair [emphasis mine] 2021-2022, United States Department of State and Norwegian Ministry of Foreign Affairs

…

Paul Arthur Berkman is science diplomat, polar explorer and global thought leader applying international, interdisciplinary and inclusive processes with informed decisionmaking to balance national interests and common interests for the benefit of all on Earth across generations. Paul wintered in Antarctica [emphasis mine] when he was twenty-two, SCUBA diving throughout the year under the ice, and then taught a course on science into policy as a Visiting Professor at the University of California Los Angeles the following year, visiting all seven continents before the age of thirty.

…

Hidden diversity

While the panel is somewhat Ottawa-centric with a strong bias towards the US and Europe, there are some encouraging signs.

Beck’s experience in Asia and Berkman’s in the polar regions is good to see. Dufour has written the Canada chapter in two (2015 and 2021) UNESCO Science Reports and offers an excellent overview of the Canadian situation within a global context in the 2021 edition (I haven’t had the time to view the 2015 report).

Economist Audretsch and FinTech entrepreneur Van de Plassche, offer academic and practical perspectives for ‘innovation’ while Perry and Welsh both offer badly needed (Canada has been especially poor in this area; see below) security perspectives.

The rest of the panel offers what you’d expect, extensive science policy experience. I hope Gattinger’s experience with arts/cultural policy will enhance this project.

This CCA project comes at a time when Canada is looking at establishing closer links to the European Union’s science programmes as per my May 11, 2022 posting: Canada’s exploratory talks about joining the European Union’s science funding programme (Horizon Europe).

This project also comes at about the same time the Canadian federal government announced in its 2022 federal budget (covered in my April 19, 2022 posting, scroll down about 25% of the way; you’ll recognize the subhead) a new Canadian investment and Innovation Agency.

Notes on security

Canada has stumbled more than once in this area.The current war waged by Russia in Ukraine offers one of the latest examples of how state actors can wage damage not just in the obvious physical sense but also with cyberattacks. The US suffered a notable attack in May 2021 which forced the shutdown of a major gas pipeline (May 9, 2021 NBC news report).

As for Canada, there is a July 9, 2014 Canadian Broadcasting Corporation news report about a cyberattack on the National Research Council (NRC),

A “highly sophisticated Chinese state-sponsored actor” recently managed to hack into the computer systems at Canada’s National Research Council, according to Canada’s chief information officer, Corinne Charette.

…

For its part, the NRC says in a statement released Tuesday morning that it is now attempting to rebuild its computer infrastructure and this could take as much a year.

The NRC works with private businesses to advance and develop technological innovations through science and research.

…

This is not the first time the Canadian government has fallen victim to a cyberattack that seems to have originated in China — but it is the first time the Canadian government has unequivocally blamed China for the attack.

…

In September 2021 an announcement was made about a new security alliance where Canada was not included (from my September 17, 2021 posting),

Wednesday, September 15, 2021 an announcement of a new alliance in the Indo-Pacific region, the Three Eyes (Australia, UK, and US or AUKUS) was made.

Interestingly all three are part of the Five Eyes intelligence alliance comprised of Australia, Canada, New Zealand, UK, and US. Hmmm … Canada and New Zealand both border the Pacific and last I heard, the UK is still in Europe.

…

I mention other security breaches such as the Cameron Ortis situation and the Winnipeg-based National Microbiology Lab (NML), the only level 4 lab in Canada in the September 17, 2021 posting under the ‘What is public safety?’ subheading.

It seems like there might be some federal movement on the issues assuming funding for “Securing Canada’s Research from Foreign Threats” in the 2022 federal budget actually appears. It’s in my April 19, 2022 posting about 45% of the way down under the subheading Research security.

I wish the panel good luck.

Hybrid bacterial genes and virus shell combined to create ‘nano reactor’ for hydrogen biofuel

Leave a reply

Turning water into fuel may seem like an almost biblical project (e.g., Jesus turning water to wine in the New Testament) but scientists at Indiana University are hopeful they are halfway to their goal. From a Jan. 4, 2016 news item on ScienceDaily,

Scientists at Indiana University have created a highly efficient biomaterial that catalyzes the formation of hydrogen — one half of the “holy grail” of splitting H2O to make hydrogen and oxygen for fueling cheap and efficient cars that run on water.

A Jan. 4, 2016 Indiana University (IU) news release (also on EurekAlert*), which originated the news item, explains further (Note: Links have been removed),

A modified enzyme that gains strength from being protected within the protein shell — or “capsid” — of a bacterial virus, this new material is 150 times more efficient than the unaltered form of the enzyme.

…

“Essentially, we’ve taken a virus’s ability to self-assemble myriad genetic building blocks and incorporated a very fragile and sensitive enzyme with the remarkable property of taking in protons and spitting out hydrogen gas,” said Trevor Douglas, the Earl Blough Professor of Chemistry in the IU Bloomington College of Arts and Sciences’ Department of Chemistry, who led the study. “The end result is a virus-like particle that behaves the same as a highly sophisticated material that catalyzes the production of hydrogen.”

…

The genetic material used to create the enzyme, hydrogenase, is produced by two genes from the common bacteria Escherichia coli, inserted inside the protective capsid using methods previously developed by these IU scientists. The genes, hyaA and hyaB, are two genes in E. coli that encode key subunits of the hydrogenase enzyme. The capsid comes from the bacterial virus known as bacteriophage P22.

The resulting biomaterial, called “P22-Hyd,” is not only more efficient than the unaltered enzyme but also is produced through a simple fermentation process at room temperature.

The material is potentially far less expensive and more environmentally friendly to produce than other materials currently used to create fuel cells. The costly and rare metal platinum, for example, is commonly used to catalyze hydrogen as fuel in products such as high-end concept cars.

“This material is comparable to platinum, except it’s truly renewable,” Douglas said. “You don’t need to mine it; you can create it at room temperature on a massive scale using fermentation technology; it’s biodegradable. It’s a very green process to make a very high-end sustainable material.”

In addition, P22-Hyd both breaks the chemical bonds of water to create hydrogen and also works in reverse to recombine hydrogen and oxygen to generate power. “The reaction runs both ways — it can be used either as a hydrogen production catalyst or as a fuel cell catalyst,” Douglas said.

The form of hydrogenase is one of three occurring in nature: di-iron (FeFe)-, iron-only (Fe-only)- and nitrogen-iron (NiFe)-hydrogenase. The third form was selected for the new material due to its ability to easily integrate into biomaterials and tolerate exposure to oxygen.

NiFe-hydrogenase also gains significantly greater resistance upon encapsulation to breakdown from chemicals in the environment, and it retains the ability to catalyze at room temperature. Unaltered NiFe-hydrogenase, by contrast, is highly susceptible to destruction from chemicals in the environment and breaks down at temperatures above room temperature — both of which make the unprotected enzyme a poor choice for use in manufacturing and commercial products such as cars.

These sensitivities are “some of the key reasons enzymes haven’t previously lived up to their promise in technology,” Douglas said. Another is their difficulty to produce.

“No one’s ever had a way to create a large enough amount of this hydrogenase despite its incredible potential for biofuel production. But now we’ve got a method to stabilize and produce high quantities of the material — and enormous increases in efficiency,” he said.

The development is highly significant according to Seung-Wuk Lee, professor of bioengineering at the University of California-Berkeley, who was not a part of the study.

“Douglas’ group has been leading protein- or virus-based nanomaterial development for the last two decades. This is a new pioneering work to produce green and clean fuels to tackle the real-world energy problem that we face today and make an immediate impact in our life in the near future,” said Lee, whose work has been cited in a U.S. Congressional report on the use of viruses in manufacturing.

Beyond the new study, Douglas and his colleagues continue to craft P22-Hyd into an ideal ingredient for hydrogen power by investigating ways to activate a catalytic reaction with sunlight, as opposed to introducing elections using laboratory methods.

“Incorporating this material into a solar-powered system is the next step,” Douglas said.

Combining gold and palladium for catalytic and plasmonic octopods

Leave a reply

Hopefully I did not the change meaning when I made the title for this piece more succinct. In any event, this research comes from the always prolific Rice University in Texas, US (from a Nov. 30, 2015 news item on Nanotechnology Now),

Catalysts are substances that speed up chemical reactions and are essential to many industries, including petroleum, food processing and pharmaceuticals. Common catalysts include palladium and platinum, both found in cars’ catalytic converters. Plasmons are waves of electrons that oscillate in particles, usually metallic, when excited by light. Plasmonic metals like gold and silver can be used as sensors in biological applications and for chemical detection, among others.

Plasmonic materials are not the best catalysts, and catalysts are typically very poor for plasmonics. But combining them in the right way shows promise for industrial and scientific applications, said Emilie Ringe, a Rice assistant professor of materials science and nanoengineering and of chemistry who led the study that appears in Scientific Reports.

“Plasmonic particles are magnets for light,” said Ringe, who worked on the project with colleagues in the U.S., the United Kingdom and Germany. “They couple with light and create big electric fields that can drive chemical processes. By combining these electric fields with a catalytic surface, we could further push chemical reactions. That’s why we’re studying how palladium and gold can be incorporated together.”

The researchers created eight-armed specks of gold and coated them with a gold-palladium alloy. The octopods proved to be efficient catalysts and sensors.

A Nov. 30, 2015 Rice University news release (also on EurekAlert), which originated the news item, expands on the theme,

“If you simply mix gold and palladium, you may end up with a bad plasmonic material and a pretty bad catalyst, because palladium does not attract light like gold does,” Ringe said. “But our particles have gold cores with palladium at the tips, so they retain their plasmonic properties and the surfaces are catalytic.”

Just as important, Ringe said, the team established characterization techniques that will allow scientists to tune application-specific alloys that report on their catalytic activity in real time.

The researchers analyzed octopods with a variety of instruments, including Rice’s new Titan Themis microscope, one of the most powerful electron microscopes in the nation. “We confirmed that even though we put palladium on a particle, it’s still capable of doing everything that a similar gold shape would do. That’s really a big deal,” she said.

“If you shine a light on these nanoparticles, it creates strong electric fields. Those fields enhance the catalysis, but they also report on the catalysis and the molecules present at the surface of the particles,” Ringe said.

The researchers used electron energy loss spectroscopy, cathodoluminescence and energy dispersive X-ray spectroscopy to make 3-D maps of the electric fields produced by exciting the plasmons. They found that strong fields were produced at the palladium-rich tips, where plasmons were the least likely to be excited.

Ringe expects further research will produce multifunctional nanoparticles in a variety of shapes that can be greatly refined for applications. Her own Rice lab is working on a metal catalyst to turn inert petroleum derivatives into backbone molecules for novel drugs.
